Retrieving values from a dictionary using namespacing

Hi all,

 

I would like to understand the following behaviour:

If the dictionary values are all atoms of the same type, treating the dictionary as a namespace will throw an error when retrieving a value. Otherwise it seems to work ok.

 

q)dict:FAWFfawersesgdgrgr!til 5 q)dict FAWF | 0 faw | 1 erses| 2 gdgr | 3 gr | 4 q)dict.gr 'gr [0] dict.gr ^ q)dict:FAWFfawersesgdgrgr!(2;44i;54.7;fs;"ff") q)dict FAWF | 2 faw | 44i erses| 54.7 gdgr | fs gr | “ff” q)dict.gr “ff” q)dict:FAWFfawersesgdgr`gr!enlist each til 5 q)dict FAWF | 0 faw | 1 erses| 2 gdgr | 3 gr | 4 q)dict.gr ,4

 Thanks,

Eoghan

Probably because this syntax is only intended to use with regular namespaces (whose names begin with a dot). When you create a namespace it always has a mixed list in its values because a  ` | :: item is implicitly inserted into it. So the lookup code might be written with the assumption that this always needs to be the case.
